Input a string and change it is that the characters are placed in alphabetical order.

For example, the string "motivate" should be changed to "aeimottv"

#include <stdio.h>
#include <string.h>
#include <conio.h>
#define SIZE 100
 
void main()
{
	char str[SIZE], aux;
	int i, j, minpos;
 
	printf("Enter  a string : ");
	gets(str);	
 
	for(i=0; str[i]!='\0';i++)
	{
		minpos=i;
		for(j=i+1; str[j]!='\0';j++)	
			if(str[j]<str[minpos])
				minpos=j;
		if(minpos!=i)
		{
			aux=str[minpos];
			str[minpos]=str[i];
			str[i]=aux;
		}
	}

	printf("In alphabetical order: %s\n",str);

	getch();
}
